Setting a retention policy. @ThomDietrich I hope this post makes sense. influxdb]] ## Works with InfluxDB debug endpoints out of the box, ## but other services can use this format too. InfluxDB offers two features - continuous queries (CQ) and retention policies (RP) - that automate the process of downsampling data and expiring old data. By default, Telegraf will insert your new data into a database called telegraf with a retention policy named autogen. The path to the script is as follows: The "-dbrp" argument specifies the InfluxDB "database retention policy". autogen, exactly how you would reference it when writing your InfluxQL query. Continuous Query Use Cases Downsampling and Data Retention. Example retention policy: Create retention policy “one_day_by_hour” duration 1d shard duration 1h. In this tutorial we will learn how to install InfluxDB on these three systems. The java doc does indicate we should use the query method in place of these helper methods, but I cannot confirm what the right way to write these queries is. IoT with InfluxDB, Telegraph and Grafana on the Raspberry Pi 3 In the internet I stumbled on the following beautiful Grafana Dashboard and wanted to try it out myself, of course. xml and implementation file I_VeraFlux1. See Database Management for retention policy management. This will help keep your database from being bloated by 30s system metrics. So in a nutshell, a retention policy dictates for how long data will be kept and stored and if you're using InfluxDB Enterprise, how many of. "cq_dht22_1h" FROM dht22 GROUP BY time ( 1 h ), gatewayId END. Queries must be "fully-qualified," and include both the database and retention policy. Bring your laptop ready to go(*) and get started with InfluxDB 2. By default, the retention policy is ‘autogen‘ and will. That retention policy holds the data for infinity which implies a shard data duration of 168h. Recording and visualising symfony response times with InfluxDB and Grafana 01/04/2018 - LINUX, SYMFONY In this example we are going to record how long it takes to return a response from controller methods and visualise the data. This should only set to no used on personally controlled sites using self-signed certificates. retention-policy = “” bind-address = “:2003” protocol = “tcp” consistency-level = “one” once you are done with changes restart the influx DB to fetch the new configurations as below. It covers the database "icinga" and sets a retention policy of "autogen". The InfluxDB process must not be running during a restore. This is a reference for the Influx Query Language ("InfluxQL"). We will use Grafana's official docker image to launch Grafana server in our local machine, and connect and show the memory usage data from influxdb as a data source. influxDBDatabase: The name of the database that we define in InfluxDB.
